and MCUXpresso. Currently I try to let the LED blink. I can connect with the board and debugging, but nothing happens, even when ein use the "Board_LED_Set" funktion. MCUXpresso and the Debugger are showing, that values in the GPIO Registers are changed. Anyone a suggestion?

From your following code, it appears that the LED is connected to P0_22(GPIO0_22), if it is the case, pls use the code.

anyway, pls check which pin is connected to LED.
